UTT HINGE @rlglnal application filed. December 12, 1918, serial No. 344,276. Patent No. 1,40%361. Divided and this application filed February 17, 1928. Serial No. 619,663.

To all whom it may concern.

it known that I, FRANK A. a citizen of the United States of America, residing at Plainvillc, Hartford County, Cons necticut, have invented a new and useful Butt Hinge, of whichthe following is a I specification.

My invention relates particularly ,to what are commonly termed all bearing hinges lo and the present a plication is --a division from #344,276, ed December 12, '1919,

- now Patent #1,409,461. In the former case I have broadl claimed a hinge in which a protected all bearing is secured is; in place on chuckle of the hinge and specifically claimed a pair of ball beariliigs held in place on opposim' ends of a knuc e.

s resent app cation has for its main object t more s ecific protection of the so invention describe in my former case and illustrated in Fi re 4 of said Patent #1,409,461. In t 's construction the ball bearing unit is secured adequatelyin place so that the hinge ma be handled without 25 danger of losing or isplacing the bearing .5 suches? an unit but yet the bearing unit may be detached when desired for the purpose of inspection, repair, or renewal.

The particular form of construction illustrated employsone or more spring fingers with he engagin in a recess for detachably and out y securing the bearunit in i I Fig. e is'a detail side v ew of one of the 0 Fig. 5 is a se arate vertical sectional view of one of the lrnuckles adapted to receive the ball in unit of Fig. 4.

The I leaves 5 and 6 maybe rovid with an suitable number of knuc les sand. the parts ma be se- .5 gather by any suitable orm of tle e anti-friction or ball bearing unit in Fig. 4 and shown in cannot be withdrawn from the @uc section in Fig. 3 has two washer like hell races 10 and 11 with anti-friction members such as the balls 12 between them. These washers or ball races are held together and protected by a casing consisting preferably of the two parts 13 and 14. This casing is preferably formed of non-corrosive sheet metal spun, drawn, or otherwise formed to the desired shape. The parts are sciently loosely connected so that one or the other of the ball moss is 'free to turn with respect to the other. The outer part of the casing or housing is preferably finished to give a neat and pleasing appearance. The parts are so constructed and proportioned that they rotrude but little laterall of the knuc es and so as to bring the alls, into a position to afiord the maximum support with a mmimum ossibility of distortion of the ball races an knuckles.

The inner part 14 of the housing or casing,

has an extension adapted to the inside of one of the knuckles. In the form shown this extension has two spring fingers 15 within the bore 16 of the knuckle 8. The lower end of the tubular member la is provided with anoutwardly extending flange or beadl'? which fits within the groove or recess 18 of the knuckle. It will be obvious with respect to Fig. 3 that the bearing unit e except by disengaging the flange 17 from the groove 18. s, of course, can be accomlished by the use of a suitable tool. I preer, however, to form the groove 18 with an inclined shoulder 19 so that it is possible to.

automatically disenge the flangel? b simply ushm y or I.) mg the hearing t vertical y so t at has flanges 17 will auto maticall be forced inward along the inclined s oulder 19 and thus disengaged. ll

have formeclthe r' or 15 by sim ly slotting orfsplittt at 20 the tubular 'n- 14 but it be obvious that this might be accomp "shed in ny other ways.

It will be obvious that any of the knuckles of the 1 w e y be provided with hearing units suc as o bed, but in this case I have only illustrated two PM:

units, one attached to the knuckle 8 1i ltlil another unit 21 attached to the nos '1. Obviously, either leaf of such a hinge may be attached to the door and still secure adequate anti-irictional support.

The construction as herein shown is of particular advantage in that it not only may be Y economically manufactured and easily assembled, but there is no danger of the bearings being lost or misplaced or assembled wrong side up as is possible with the ordinary loose type of ball bearing employed prior to my invention. This 'construction also permits of a maximum size of bearing for a given size hinge knuckle without requiring unsightly or awkward projections. As the ball races are arranged entirely outside of the knuckles it is not necessary to weaken the knuckles by cutting grooves as has beendone in some constructions. p

A carpenter may take the leaves apart for the purpose-of attaching them to a door frame and door without danger of misplacing or losing the parts, but on the other hand in the form of construction herein shown it is comparatively easy .to detach the bearing units when necessary 'for the purpose of repair or replacement.

' I wish it understood that the terms of the claims are to be construed as descriptive rather than in limitation, except as required by the prior art. It should be understood, however, that although modifications may be made, the connection between the bearing unit and the knuckleor hinge leaf should.

be sufficiently positive to prevent the bearing unit from being accidently dislodged or dropped off in the ordinary handling and erection of the hinge. Where spring fingers are employed for holding the bearing unit in place they should be strong enough to reuire some substantial force in disengaging t em.

I prefer to enclose the outer and inner edges of the ball races substantially as shown so as to revent water and dirt from working in an corroding or clogging the ball bearing and interfering with the proper freedom of action. 7

I claim:

1. A hinge comprising leaves having interfitting knuckles and an anti-friction device consisting of bearing washers with interposed anti-friction members and spring means for detachably securing said device to one leaf. I

2. A hinge comprising leaves having cooperating knuckles and an anti-friction device between adjacent knuckles consisting of bearing washers, bearing members between said washers, a casing connecting the outer edges of said washers, and a tubular lining havin a spring .finger detachably securing said evice to one knuckle.

3. A hinge comprising leaves having 00- operating knuckles, an anti-friction device com rising bearing washers .and bearing mem rsbetween said washers, and a tubu- 65,.1ar lining having an. extension split to provide spring fin era for detachably securing said device in pdace.

4 A hin e comprising means having 00* operating 'uckles with.- a roove in one knuckle and an anti-friction evice comprising washers between adjacent knuckles, bearings between said washers, and a casing for said washers having a finger detachably engaged in said groove.
